It still takes clearing time - 4 to 5 business days.
In the States, if you transfer, you transfer immediately being a check or wire instruction, but then they charge you for account management (though I find it far better than over here where the banks screw up - I found out one of them, Lloyds, had no ISO 9000 quality control systems in place and I believe RBS hasnt either).
However, back to the point, they use yourmoney on the overnight and short term markets where they can get %s way above the interbank rates, so its all about cashflow management so they use ours.
Should see it Tuesday or Wednesday morning on her account.
